Because the climate is the decisive factor for coffee planting, the origin of coffee trees in Ethiopia in Africa is more suitable for growing in the tropics or subtropics, so the area between 25 degrees north and south latitude is most suitable for planting coffee. This coffee-producing area is generally referred to as the "coffee belt" or "coffee zone".

However, not all the land located in this area can cultivate excellent coffee trees. The most ideal planting conditions for coffee trees are: a warm climate with a temperature between 15-25°C, and the annual rainfall must reach 1500-2000 mm. At the same time, the rainfall time should be able to match the flowering cycle of coffee trees. Of course, in addition to the coordination of seasons and rainfall, there must be fertile soil. The most suitable soil for growing coffee is well-drained, pozzolanic fertile soil.

In addition, although sunlight is an indispensable element for the growth and fruiting of coffee, too strong sunlight will affect the growth of coffee trees, so each production area usually plants some shade trees, generally planting bananas, and mangoes, legumes, and other trunks taller plants. The ideal altitude is 500-2000 meters.

Therefore, Jamaican Blue Mountain coffee is the best quality coffee grown at an altitude of 800-1200 meters. It can be seen that the conditions for cultivating high-quality coffee are quite strict: altitude, sunlight, rainfall, soil, temperature, as well as the way and production process of coffee beans, all affect the quality of the coffee itself.
